    I have the new unibody white Macbook and have calibrated twice. I currently only have 9 cycle on my battery. My battery currently shows 92% current battery capacity at 5053 mAh and original capacity at 5450 mAh. What is wrong with my battery? Or is it Coconut Battery?

    do you actually use the battery or do you run it off ac power most of the time?

    make sure you let the electrons flow a bit

    I do let my battery run most of the time. It's rarely at full capacity.

    So is my battery just one with slightly lower capacity than normal? I've read other posts where people with a few hundred cycles that still have 95% capacity and up!

    it's fine. my macbook only goes up to 98% 95% or 99% if i unplug the charger from my macbook then plug it back in after having 89% or somewhat battery life gone it'll fully charge up.

    My Battery did the same thing - I think its part of the "breaking - in" process, I think the battery capacity was even showing 93% at one point when it was "fully charged". But now that I'm at over 100 cycles it seems to have stabilized and the capacity has gone back to 99% and 98% of the original battery charge. (These stats all using coconutBattery).

    Just make sure you keep your battery well maintained by once a month letting it run completely flat and then letting it rest for 24hrs if you can (tough for me because my machine is in daily use) and then charging it fully again before turning on - this is a practice recommended by Apple: this page even gives you a reminder you can add into iCal.

    Don't worry I'm sure your battery is fine.

    Thanks guys. Regardless of what CoconutBattery is showing, I'm still getting about 5 hours of battery time with iTunes, Safari, Adium, light web browsing using wifi, BT off, and 75% brightness. That sure beats almost any other laptop out there.

    Also, would you recommend that I routinely fully drain the battery each time, then charge it up fully?
